Bruno's Hitmonlee and Hitmonchan charge forward, as do Lt. Surge's Electabuzz and Bill's Vulpix. Vulpix and Electabuzz shove Hitmonlee and Hitmonchan, who land on their feet on the Onix bridge. Hitmonchan unleashes a barrage of Comet Punches, and Hitmonlee attacks with a powerful Rolling Kick.
Yellow and Blaine, seeing how bad the situation is for Bill and Lt. Surge, have Pika and Rapidash use Thunder Shock and Fire Spin, respectively. However, not even a dent appears on the wall. Bruno tells them to leave, but Yellow and Blaine keep trying to break the wall. For punishment, an Onix wraps around them. On the other side of the wall, Lt. Surge and Bill come up with a battle strategy to face Bruno's Machamp. When Machamp comes to Bill and Lt. Surge, they run away.
Next to Machamp, two hidden Poké Balls open, and Bill's Exeggcute and Lt. Surge's Electrode come out. Exeggcute uses Egg Bomb and Barrage to shoot out floating groups of eggs. Then, Electrode uses Self-Destruct to make the groups of eggs explode, which causes the Onix to thrash in pain, sending Bruno, Machamp, Hitmonlee, Hitmonchan, Bill, Exeggcute, Vulpix, Lt. Surge, and Electrode down. Four Magneton appear and stop Lt. Surge, Bill, and their Pokémon from falling by creating a magnetic pyramid around them (other than Lt. Surge, who is climbing up on a Magneton). Bill looks down at the acid below and knows that if Bruno did fall in, he couldn't have survived.
